Our take on the TCL 85 Class Q5K Series 4K UHD LED Smart Google TV

The TCL Q5K is an 85-inch 4K LED smart TV running Google TV, with HDR support and a 2025 release. It is a budget big-screen set aimed at people who want maximum size for the money rather than premium picture quality. At $749.99 at Best Buy as of November 7, 2026, it sits at the low end of what an 85-inch 4K TV costs, so the price is strong for the size.

Questions and answers

Is the TCL Q5K good for movies and sports?: It handles both well for the price. The 85-inch screen makes sports and movies feel big, but dark scenes lose detail because it is a standard LED panel without local dimming.
How does it compare with TCL's QM6K or QM7K?: Those are mini-LED sets with much better brightness and contrast, and they cost more. The Q5K trades picture quality for size at a low price.
Does it support HDR formats?: Yes, it supports HDR. Expect a modest brightness boost rather than a dramatic one, since this is an entry-level LED panel.
What is in the box?: The TV, a stand, a remote and power cable. A wall mount and HDMI cables are not included.
When is it cheapest?: Large TVs usually drop around Black Friday and before the Super Bowl. At $749.99 as of November 7, 2026, it is already near the bottom of the 85-inch market.
Will it fit my wall or stand?: It is 85 inches diagonally, so measure your space first. Check the VESA pattern and weight before buying a wall mount.
Where is the TCL 85 Class Q5K Series 4K UHD LED Smart Google TV cheapest?: At Best Buy, for $749.99, as of our latest check.
